Answer:
44 Minutes
Explanation:
If he takes for minutes per lap than some easy multiplication will do the job to find out how long 11 laps will take.
If he keeps running a lap in 4 minutes for every lap up, until the 11th lap, that means we multiply 11 times 4.
Another example being, if I run 1 lap in 1 minute then if I ran 2 laps it would take me 2 minutes, because 1 times 2 is 2, and so fourth for each lap. So if I ran 11 laps it would take me 11 minutes because 11 times 1 is 11.
